Selective transportation of molybdenum from model and ore through poly inclusion membrane

Abstract

The extraction of molybdenum from the aqueous solution through poly inclusion membrane (PIM) containing tri-caprylylmethylammonium chloride (Aliquat-336) as a carrier has been investigated. A solution of molybdenum in phosphoric acid was used as a feed side while sodium hydroxide was used as stripping reagent. The results indicate that maximum flux value was obtained at 0.16 M Aliquat-336. Increase in H₃PO₄ concentration from 0.05 to 1.5 M results into an increase in molybdenum ions. The maximum flux of 3.00×10⁻⁶ mol/m²s through PIM was found at 1.5 M H₃PO₄. The optimized conditions were applied for removal of Mo(VI) from ore and more than 97 % Mo(VI) was extracted.
